Chrysanthemum plant named ‘Zanmubonita Yellow’

ABSTRACT

A new and distinct chrysanthemum plant named ‘Zanmubonita Yellow’ is disclosed, it is characterized by its medium sized, double type blooms with yellow color ray florets and response time of 7 weeks. The new plant is normally used for commercial cut flower production.

Botanical designation: Chrysanthemum x morifolium Ramat.

Cultivar denomination: ‘Zanmubonita Yellow’.

RELATED CULTIVARS

‘Zanmubonita Yellow’ is a mutant plant of ‘Zanmubonita’ (unpatented).

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar ofchrysanthemum, botanically known as Chrysanthemum x morifolium, andreferred to by the denomination ‘Zanmubonita Yellow’; the description isbased on plants of about 10 weeks old.

‘Zanmubonita Yellow’ is a product of a breeding and selection program toproduce new chrysanthemum cultivars for cut flower commercialapplications. The new plant cultivar is a naturally whole plant mutantof a parent chrysanthemum named ‘Zanmubonita’ (unpatented).

A comparison with the parent is made in the section ‘DESCRIPTION OF THEINVENTION’ below. The new cultivar was discovered as a whole plantmutation in June 2014 by Henricus Cornellius Maria Jacobs in acontrolled environment (greenhouse) in Valkenburg Z-H, The Netherlands.The first act of asexual reproduction of ‘Zanmubonita Yellow’ wasaccomplished when vegetative cuttings were taken from the initialselection and propagated further in Valkenburg Z-H, The Netherlands.

SUMMARY OF THE INVENTION

The present invention is a new and distinct variety of a cut typechrysanthemum bearing medium sized double type blooms with yellowray-florets and a response time of seven weeks.

BRIEF DESCRIPTION OF THE DRAWINGS

The present invention of a new and distinct variety of chrysanthemum (ofabout 10 weeks) is shown in the accompanying drawings, the color beingas nearly true as possible with color photographs of this type.

FIG. 1 shows a plant of the cultivar in full bloom.

FIG. 2 shows the various stages of bloom of the new cultivar.

FIG. 3 shows the foliage of the new cultivar.

DESCRIPTION OF THE INVENTION

The observations and measurements were gathered from plants grown inAugust to September 2016 in a greenhouse in Valkenburg Z-H, theNetherlands in a photo-periodic controlled crop under conditionsgenerally used in commercial practice. The greenhouse temperaturesduring this crop were at day-time between 18° C. and 25° C. and at night20° C. After a long day period of 14 days the photo-periodic responsetime in this crop was 49 days. After the long day period to floweringgrowth retardants (Alar) were applied 2 to 3 times in an average dose of2.5 gram/liter water. No tests were done on disease or insect resistanceor susceptibility. No tests were done on cold or drought resistance.This new variety of chrysanthemum has been found to retain itsdistinctive characteristics throughout successive propagations howeverthe phenotype may vary significantly with variations in environment suchas light intensity and temperature.

From the cultivars known to inventor the most similar existing cultivarin comparison to ‘Zanmubonita Yellow’ is ‘Zanmubonita’. When‘Zanmubonita’ and ‘Zanmubonita Yellow’ are being compared the followingdifferences and similarities are noticed: The difference of‘Zanmubonita’ and ‘Zanmubonita Yellow’ is ray floret color. For thatcharacteristic ‘Zanmubonita Yellow’ has been selected out of‘Zanmubonita’; ray florets of ‘Zanmubonita Yellow’ are yellow, whilethose of ‘Zanmubonita’ are white. All other characteristics of‘Zanmubonita’ and ‘Zanmubonita Yellow’ are similar. A second similarvariety is ‘Sunny Eurobelle’ (unpatented), which differs ininflorescence size with ‘Zanmubonita Yellow’. Inflorescences of ‘SunnyEurobelle’ are smaller in size than those of ‘Zanmumbonita Yellow’.

The following is a description of the plant and characteristics thatdistinguish ‘Zanmubonita Yellow’ as a new and distinct variety.

The color designations are taken from the plant itself. Accordingly, anydiscrepancies between the color designations and the colors depicted inthe photographs are due to photographic tolerances. The color chart usedin this description is: The Royal Horticultural Society Colour Chart,edition 2001.
